WERHAM, OF SOUTH NYAOK, NEW YORK.

DETACHABLE HEEL.

To all whom z't may concern:

Be it known that I, SILVESTRO MILANO, a citizen of the United States, residing in the city of New York, borough of the Bronx, county and State of New York, have invented a 'certain new and useful Detachable Heel, of which the following is'a specification.

This invention is a detachable heel or sole for all kinds of foot wear, moreparticularly for boots and shoes.

or shoe to detach the bottom layer of'a sole or heel which has worn down either in the middle or on the outer edge, and to replace the same by a new or fresh layer of any suitable material, the operations being performed without requiring tlie services of a skilled workman.

Among the novel featuresof the invention may be'. mentioned the following. First, novel attaching means which preclude either a lateral or separating movement of the re.

placed member with reference to the xed part of the sole or heel; second, a Vnovel means for telescopi'ng the attaching members together prior to locking,'and, third, novel means for anchoring the material to one of the attaching mem rs.

Other features of the invention will be apparent from the hereinafter dgtailed description.

Inthe accompanying drawings, I have illustrated different practical embodiments of the invention, but the constructions shown therein are to be understood asillustrative,

only, and' notas defining the limits of theinvention.

Figure 1 is a side elevation, partly in section, showing the lift applied to the heel of an ordinary shoe. Fig. 2 is a bottom plan of Fig. 1 with the lift member removed. Fig. 3 is a front elevation of the member shown in Fig. 2. Fig. 4 is a plan view of the heel lift of Fig. 1.'. verse section through the heel lift 'on the line 5-5 of Fig. 4.

This invention is illustrated as applied 5, the invention p comprises interlocking members inthe form of plates A, B which coperate with each other to securel the heel lift to the shoe. Plate A is'constructed of any suitable material, preferably of sheet vmetal which maybe tempered if so desired,

and Jthis plate is provided along its edge with an in turne'd` flange 20,` the walls of -said flange being integrall with the plate and bent preferably at an oblique angle thereto, thereby forminga chamber between Patented Jan. 16, 1917. Application leii December 13,1911. Serial No. y665,464. l

.65 Figs. 10 and V-11 are a longitudinal section voperating memberof Figs. 10 and 11,'a-ndon 4 the plate andL -the portion of theheel orlift to which the plate is applied. .This flange' extendsV substantially around the plate eX-' cept at the front 4edge thereof, where'they flange fis omitted to permit ofthe insertion of a. filler :10of any suitable material, suchas leather', wood or a composition of material into the chamber formed by the flanges 20 ofy the plate,.the filler serving\ a"s` a core' or support for plateA. This plate A, may be provided, also, with lips 21, "which lips are .integral with the'inturnedilange 20,

4,and are bent at '.anvangle to said angeso that the lips lie -in a plane l parallel to the plate A'. The-core or filler wis inserted into plate A, and it is retained .between said plate and lips 21 bysuitable Securing means,

such as screws 22, which pass through plate A, filler lips 21, and into the main portion of the heel C, thereby rigidly securing plate A to the shoe. It is obvious, however, that these lips can be omitted without affecting the operation of the device.

Coperating plates A, B may beof any desired shape or contour, but in the drawings they are shown as having straight sides, with one end substantially semi-circulary and the other end of a shape to conform to the front edge of an ordinary heel lift. The plate A is provided with an aperture 23, preferably in the semi-circular part of the plate and extending into the flange 20, the purpose of which aperture 23 will be presently explained. At the other end of plate A, preferably about opposite to the aperture 23, said plate is provided with parallel slits 24, to produce a. tongue 25. A stud 26 is integral with the tongue, said stud being below the horizontal plane of plate A. This stud 26 and tongue 25 operate as a spring latch to lock the platesA and B in'tlieir assembled positions, the straight edge of stud 26 engaging with a straight edge of an aperture 27 in plate B, thereby preventing accidental removal of plate B from plate A. It is obvious that the latch may be reversed as to plates A and B without affecting the operation of the device. However, the latch may be of any other desired form, as in Fig. 15 the stud 26 is shown as substantially triangular.

Plate B in Figs. 4 and 5, is applied to the l heel lift D. This plate B is similar in general appearance to plate A in that it is provided with straight sides, one end semi-circular and the other end slightly curved to conform to the shape of the heel. This plate is provided with -a flange 28 substantially around the plate except at 'the slightly curved edge thereof, and this flange is bent at an oblique angle to the plate, as in the case of plate A, so that when it is ldesiredto assemble plates A and B to the position shown in Fig. 1, the flange 28 of plate B will inclose flange 20 of plate A, said plate B thereby substantially inclosing plate A.

The coperating flanges 20, 28 operate to] prevent movement of,y the heel lift relative to the shoe, t'. e., the two flanges preclude i literal separation of the lift from the Anyl suitable means may be employed for attachmg plate B to the heel lift, but in Figs. 4 and 5 I have shown prongs 29 which are integral with plate B, said prongs being driven into the material composing the heel lift. Plate B is provided, also, with a stud a 30 which is adapted to engage with the aperture 23 of plate A, said stud and slot serv- 1ng as a thrust device. This thrust device coperates with the two plates A, B, and operates to take away a part of the strain brought upon the flanges by the twisting movement exerted by one part of the heel upon the other part of the heel. This thrust device, therefore, relieves the flanges from undue strain when'the heel is in use. It also precludes the flanges 20, 28 from becoming accidentally separated or torn apart at the rear of the heel, such for example as when a sudden vertical strain isl exerted upon the movable part .of the heel with relation to the fixed part of the heel.

In Figs. 6, 7, 8 and 9, the plate A is united to the heel lift D, and plate B is attached to heel C. VThe plate A of these figuresis similar in substantial respects to plate A of Fig. 2, except that the plate A of Fig. 8 is provided with stud 30, instead of aperture 23, and the securing lips 21 for the filler are omitted. Said plate A is provided, also, with protruding flanges 31 which are integral with, and in the same horizontall plane as, said plate A, said flanges operating to prevent the corners of the lift from becoming separated from the heel. Depending from the slightly curved edge of said plate A, and the protruding flanges 31, is a depending flange (not shown) which isadapted to fit snugly against the heel lift D, said depending flange being integral with plate A and flanges 31, and depending at a right angle therefrom. If desired, the

lift may be cut away' sufficiently to permity the depending flange tol lie flush with the front wall of heel C and lift D. The protruding flanges 31 may extend from the edge of plate A to the outer edge of heel D, as shown in AFig. 8, or said flange may be shorter, as in Fig. 11. The protruding flanges 31 lit into slots 32 in the heel C, Fig. 7, and serve to prevent the separation of the heel lift D from the heel C at the corners i of the lift. lF langes 31 and stud 30 operate produce two sections A, A2, to facilitate manufacture of the device and its easy adjustment of the parts. The art A is constructed of sheet metal, sim1lar to plate A of Fig. 2, but thepart A2 maybe made of solid metal to produce a substantial anchor.-y

age for attaching the lift to the heel. In this construction, the section A overlaps a portion of the section A2, and said platre A is provided' with suitable ears a2 through which suitable fastening means, such as screws, are passed to secure both sections A', A2 to the heel C. The protruding vide means for anchoring the plate into the' v anges 31` in this form of the device are integral with the section A2, and, as shown,

do not extend to the outer edge of the heellift D, but terminate at a point substantially ymidway between the edge of the lift and the edge of plate A3. t

In Figs. 13 14 and 15, the plate A3 of the device is substantially similar to plate A of Fig. 2, and is secured directly to the heel C, as shown in Fig. 13.v Coperating plate B3 is similar 'in many respects to plate B of Fig. 4,'except that plate B3 is designed to' be used with a lift of. special material, such as wood,

rubber, concrete preparation, or other coml Aposition of materials. When the lift is made ofl rubber, or a composition, the plate B3 is molded into the material, thereby embedding the anchoring plate B3 into the material composing the lift. This plate is provided with upstanding prongs 33 of any desired form which are stamped from the plate and bent upwardly and outwardly to promaterial of the lift. In addition to the prongs 33 for engaging the lift, the plate B3 may be, and preferably is, provided with lugs 34, 35 of any suitable shapelor contour, said lugs b eing stamped from the main portion of the plate and bent outwardly so thatj they radiate from the plate, as shown in Figa-14 and 15. These lugs 34, 35 serve as additional anchoring means around which the composite lift is molded. The prongs 33 "and lugs 34, 35 are so securely embedded in the 'material of the lift, so that should the wearer of the shoe subject the heel to a Severe blow or. accident, the lift will not bev Vtorn from the plate.-

In applying the device to an ordinary shoe, one of the plates, for instance, plate A, is secured to the heel C by Vany suitable fastening means, such as the screws 22. The

' slightly curved end of plate B, with the lift D attached thereto, is slipped over the semicircular end of plate A so that the flange 28 of'plate B will engage and inclose fiange 20 of plate A. The lift is now pushed toward 'the toe of the shoe, t`he flanges 20, 28 operating to guide the movement of the lift until the. slightly curved front edge of the lift reglsters with the slightly curved front edge of the heel, whereupon the stud 30 of plate B will enter slot 23 of plate A, and protrufding Hanges 31 will have entered the slots 32 in lift The spring latch 26 snaps into engagement with the slot 27 as 'soon as the lift has reached the end of its forward movement, and said lift is thereby secured' against accidental removal or displacement from the heel in any direction.

To remove the lift I) from heel C, for the purpose ofv replacing an old lift by a new one, or to change the lifts to different shoes,-

it is only-necessary to depress tongue 25, thus disengaging stud 26 from slot 27,

whereupon the lift may be readily removed from the heel. j

The present application, so far as it relates to Figs. 1 to 5 is, in part, a continuation of my former application Serial No. 360,892 filed March 6, 1907 and which eventuated in Letters Patent No. 995,703, granted t0 me on.

June 20, 1911.
